ABSTRACT
The antiglobulin test is the most used technique in
immunohematology and detects at least between 200
and 500 molecules of IgG, IgA molecules 120 and 30
molecules per erythrocyte IgM. Maximum intensity is
achieved when agglutination of erythrocytes coated
with more than 700 molecules over 100 IgA or IgM
molecules. This report describes several controversial
cases where the test becomes ambiguous meaning in
some cases may interfere with the reporting of results
and even delivery of units of blood products.
